It is available on Crunchyroll.

It is very good. I am way behind these guys (I'm at about episode 105 of 135).

It interesting definitely. Takes a bit to get going. There are people with magical powers (called Nen), but the anime doesn't really introduce the concept of Nen until until like 30 episodes in. Then the show picks up our main characters train, get their powers and shit starts to pop off.
